MCU-341 USB bus switching module programmer RS232/RS485/RS422

Product Description

MCU-341 is a USB bus adapter chip, which provides asynchronous serial port, printer port, read port, and commonly used 2-wire and 4-wire synchronous serial interfaces through the USB bus.

In asynchronous serial port mode, CH341 provides serial port send enable, serial port receive ready and other host speed control signals and commonly used MOOEM communication signals, which are used to expand asynchronous serial ports for computers, or directly upgrade ordinary serial port devices to USB ports.

In printer port mode, CH341 provides a standard USB printer port based on USB related specifications and Windows operating system, which is used to directly upgrade ordinary read port printers to USB ports. In read port mode, CH341 provides an 8-bit serial interface in EPP mode or MEM mode, which is used to directly input and output data in an environment without microcontroller/OSP/MCU.

In addition, the CH341A chip also hosts some commonly used synchronous serial interfaces, such as 2-wire interface (SCL line, SOA line) and 4-wire interface (CS line, SCK/CLK line, M1 S0/S01/DIN line, MOS I/SDO/DOUT line), etc.
